SAPONIFICATION

Introduction:
We used: NaOH, olive oil and Sudan III. 
With this material/elements we try to create soap.


Maerial
-Test tube rack
-Test tube
-Beaker
-Sterring rot
-Bunsen burner
-NaOH
-Olive oil
-Sudan III
-Water


Objective

1. To do the saponification
2. To make soap

Procedure:
Fisrt of all we take a test tube rack, test tube, sterring rot,... 
Later we take one test tube and put 2ml of NaOH and 2ml of olive oil. With the stirring rot, mix the solution. When you finish, put the test tube in a beaker with water and put it in the bunsen burner 10 minutes more or less. And you will see the soap (yellow).

Reaction of Saponifcation:

SECOND PART

Introduction:

We used milk and Sudan III to see if the colour change to red. 

Material:

-Test tube rack

-Test tube

-Beaker

-Dropper

-Milk

-Sudan III

Objective: 

1. Know if there are presence of lipids 

Procedure:

In the test tube we put milk but not much. Later we put some drops of Sudan III and we observe the results.

Observations: 

When whe put the Sudan III the colour of the milk change to red. That means that there are lipids in the substance.
